Example 1: Format Datetime in Python

In this example, we will get the current time and extract different parts of the date. With these we will format different kinds of date strings.

Python Program

from datetime import datetime

dt =

print(dt.strftime('Weekday short version : %a'))
print(dt.strftime('Weekday full version  : %A'))
print(dt.strftime('Weekday as a number   : %w'))
print(dt.strftime('Day of month          : %d'))
print(dt.strftime('Month Name short ver  : %d'))
print(dt.strftime('Month Name full ver   : %b'))
print(dt.strftime('Month as a number     : %m'))
print(dt.strftime('Year short version    : %y'))
print(dt.strftime('Year full version     : %Y'))
print(dt.strftime('Hour (00-23)          : %H'))
print(dt.strftime('Hour (00-11)          : %I'))
print(dt.strftime('AM/PM                 : %p'))
print(dt.strftime('Minute                : %M'))
print(dt.strftime('Second                : %S'))

print('\nFormatted Date Strings\n--------------')
print(dt.strftime('%a %d-%m-%Y'))
print(dt.strftime('%a %d/%m/%Y'))
print(dt.strftime('%a %d/%m/%y'))
print(dt.strftime('%A %d-%m-%Y, %H:%M:%S'))
print(dt.strftime('%X %x'))
